• A new CAPTCHA using sentences?

  - by Xeoncross

  I was just thinking about how recaptcha is getting harder when I thought about another posible solution. Images won't last forever so we will need something else some day - like human logic or emotion. Google and others are trying grouping images by category (find the image that doesn't belong) but that requires a large amount of images and doesn't work for the blind. Anyway, what if a massive collection of text was gathered (public-domain books from each language) and a sentence was shown to the user with 1 (or 2) words that were a select box of choices? Only computers that knew correct English/Spanish/German grammar would be able to tell which of the words belonged in the sentence. Would there be any problems with this approach? I would assume that it would be easy enough for anyone that knew the language that the sentense was displayed in to figure out the answer easier than trying to read the reCAPTCHA text. Plus, storing an insane number of sentences would only take a couple gigabytes of space and wouldn't take anywhere near the CPU time creating images/audio takes. In other words, anyone could host their own captcha system with minimal impact on system performance. Is there a problem with this approach? More specifically I'm looking for the main problem with this approach. migrated from stackoverflow

• Basket Analysis with #dax in #powerpivot and #ssas #tabular

  - by Marco Russo (SQLBI)

  A few days ago I published a new article on DAX Patterns web site describing how to implement Basket Analysis in DAX. This topic is a very classical one and is also covered in the many-to-many revolution white paper. It has been also discussed in several blog posts, listed here in historical order: Simple Basket Analysis in DAX by Chris Webb PowerPivot, basket analysis and the hidden many to many by Alberto Ferrari Applied Basket Analysis in Power Pivot using DAX by Gerhard Brueckl As usual, in DAX Patterns we try to present the required DAX formulas in a way that is easy to adapt to specific models. We also try to show a good implementation from a performance point of view. Further optimizations are always possible in DAX. However, in order to keep the model simple to adapt in different scenarios, we avoid presenting optimizations that would require particular assumptions or restrictions on the data model. I hope you will find the Basket Analysis pattern useful. Even if you do not need it today, reading the DAX formula is a good exercise to check your knowledge of evaluation contexts in DAX. For example, describing how does it work the following expression is not a trivial task! [Orders with Both Products] := CALCULATE (     DISTINCTCOUNT ( Sales[SalesOrderNumber] ),     CALCULATETABLE (         SUMMARIZE ( Sales, Sales[SalesOrderNumber] ),         ALL ( Product ),         USERELATIONSHIP ( Sales[ProductCode], 'Filter Product'[Filter ProductCode] )     ) ) The good news is that you can use the patterns even if you do not really understand all the details of the DAX formulas you are using! Any feedback on this new pattern is very welcome.

• Oracle Solaris at OpenWorld Tokyo 2012

  - by Markus Weber

  Oracle OpenWorld Tokyo will open its doors on Wednesday, April 4 2012, until Friday, April 6 2012, in Roppongi.I've you been in Tokyo as a Gaijin, or foreigner, you know exactly where that it. Many of Oracle's top executives will be there, including Larry Ellison, Mark Hurd, and John Fowler. The keynotes that they are covering will be very interesting, for sure. Now, whether you will actually be there, or not, you might still find it interesting that several great Solaris-related sessions will be held there, especially as part of the "Oracle Develop" track, such as: "Oracle Solaris 11 - Developers Need To Know" "How to build high performance and high security Oracle Database environment with Oracle SPARC/Solaris" "Oracle Solaris Tuning Contest" "IT Assets preservation and constructive migration with Oracle Solaris virtualization" And of course John Fowler's keynote "Server and Storage Systems Strategy".The complete schedule in English can be found here. We hope you can make it. If not, there will always be the San Francisco one.

• Octree implementation for fustrum culling

  - by Manvis

  I'm learning modern (=3.1) OpenGL by coding a 3D turn based strategy game, using C++. The maps are composed of 100x90 3D hexagon tiles that range from 50 to 600 tris (20 different types) + any player units on those tiles. My current rendering technique involves sorting meshes by shaders they use (minimizing state changes) and then calling glDrawElementsInstanced() for drawing. Still get solid 16.6 ms/frame on my GTX 560Ti machine but the game struggles (45.45 ms/frame) on an old 8600GT card. I'm certain that using an octree and fustrum culling will help me here, but I have a few questions before I start implementing it: Is it OK for an octree node to have multiple meshes in it (e.g. can a soldier and the hex tile he's standing on end up in the same octree node)? How is one supposed to treat changes in object postion (e.g. several units are moving 3 hexes down)? I can't seem to find good a explanation on how to do it. As I've noticed, soting meshes by shaders is a really good way to save GPU. If I put node contents into, let's say, std::list and sort it before rendering, do you think I would gain any performance, or would it just create overhead on CPU's end? I know that this sounds like early optimization and implementing + testing would be the best way to find out, but perhaps someone knows from experience?

• Dealing with 2D pixel shaders and SpriteBatches in XNA 4.0 component-object game engine?

  - by DaveStance

  I've got a bit of experience with shaders in general, having implemented a couple, very simple, 3D fragment and vertex shaders in OpenGL/WebGL in the past. Currently, I'm working on a 2D game engine in XNA 4.0 and I'm struggling with the process of integrating per-object and full-scene shaders in my current architecture. I'm using a component-entity design, wherein my "Entities" are merely collections of components that are acted upon by discreet system managers (SpatialProvider, SceneProvider, etc). In the context of this question, my draw call looks something like this: SceneProvider::Draw(GameTime) calls... ComponentManager::Draw(GameTime, SpriteBatch) which calls (on each drawable component) DrawnComponent::Draw(GameTime, SpriteBatch) The SpriteBatch is set up, with the default SpriteBatch shader, in the SceneProvider class just before it tells the ComponentManager to start rendering the scene. From my understanding, if a component needs to use a special shader to draw itself, it must do the following when it's Draw(GameTime, SpriteBatch) method is invoked: public void Draw(GameTime gameTime, SpriteBatch spriteBatch) { spriteBatch.End(); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, null, null, null, EffectShader, ViewMatrix); // Draw things here that are shaded by the "EffectShader." spriteBatch.End(); spriteBatch.Begin(/* same settings that were set by SceneProvider to ensure the rest of the scene is rendered normally */); } My question is, having been told that numerous calls to SpriteBatch.Begin() and SpriteBatch.End() within a single frame was terrible for performance, is there a better way to do this? Is there a way to instruct the currently running SpriteBatch to simply change the Effect shader it is using for this particular draw call and then switch it back before the function ends?

• Pricing: Meet or Beat?

  - by charles.knapp

  My home dishwasher started making some really interesting noises. I heard radio advertisements from two retailers who promised to meet any competitor's price. Then, I heard another retailer promising that their everyday prices beat their competitors. That got me to thinking about the power of pricing and promotions in the marketing mix (product, price, placement, promotions, and people). What is more powerful to say in a competitive market: your company will meet a similar offer, or your company will beat the others? Will you sell more if you meet or if you beat? I found that the retailer who promised to beat the others really had the best everyday pricing. Even better for me, another retailer had an exclusive promotional sale for long-term customers. Their loyalty promotion beat the best everyday discounter. So, I got the quality and performance I wanted at a tremendous price. So, I have two challenges for marketers. First, where you really have to compete on price as a dominant factor, give people strong reasons to do business with you. If you try to meet other's prices, make the leap to actually beat and not merely meet. Second, upgrade your firm's capabilities where needed. Oracle offers a complete range of great CRM software for loyalty management, marketing promotions, and pricing management that will help you to grow your business.

• What is a Data Warehouse?

  Typically Data Warehouses are considered to be non-volatile in comparison to traditional databasesdue to the fact that data within the warehouse does not change that often.  In addition, Data Warehouses typically represent data through the use of Multidimensional Conceptual Views that allow data to be extracted based on the view and the current position within the view. Common Data Warehouse Traits Relatively Non-volatile Data Supports Data Extraction and Analysis Optimized for Data Retrieval and Analysis Multidimensional Views of Data Flexible Reporting Multi User Support Generic Dimensionality Transparent Accessible Unlimited Dimensions of Data Unlimited Aggregation levels of Data Normally, Data Warehouses are much larger then there traditional database counterparts due to the fact that they store the basis data along with derived data via Multidimensional Conceptual Views. As companies store larger and larger amounts of data, they will need a way to effectively and accurately extract analysis information that can be used to aide in formulating current and future business decisions. This process can be done currently through data mining within a Data Warehouse. Data Warehouses provide access to data derived through complex analysis, knowledge discovery and decision making. Secondly, they support the demands for high performance in regards to analyzing an organization’s existing and current data. Data Warehouses provide support for an organization’s data and acquired business knowledge.  Within a Data Warehouse multiple types of operations/sub systems are supported.

• Hide email adress with JavaScript

  - by Martin Aleksander

  I read somewhere that hiding email address behind JavaScript code, could reduce spam bots harvesting the email address. <script language="javascript" type="text/javascript"> var a = "Red"; var t = "no"; var doc = document; var b = "ITpro"; var ad = a; ad += "@"; ad += b; ad += "."; ad += t; var mt = "ma"; mt += "il"; mt += "to"; var text = ""; if (text == null || text.length == 0) text = ad; doc.write("<"+"a hr"+"ef=\""+mt+":"+ad+"\">"+text+"</"+"a>"); </script> This will not display the actual email-address in the sourcecode of the page, but it will display and work like a normal link for human users. Is it any point of doing this? Will it reduce spam bots, or is it just nonsense that might slow down performance of the page because of the JavaScript?

• Timeout Considerations for Solicit Response

  - by Michael Stephenson

  Background One of the clients I work with had been experiencing some issues for a while surrounding web service timeouts.  It's been a little challenging to work through the problems due to limitations in the diagnostic information available from one of the applications, but I learned some interesting things while troubleshooting the problem which don't seem to have been discussed much in the community so I thought I'd share my findings. In the scenario we have BizTalk trying to make calls to a .net web service which was exposed as a WSE 2 endpoint.  In the process BizTalk will try to make a large number of concurrent web service calls to the application, and the backend application has more than enough infrastructure and capability to handle the load. We have configured the <ConnectionManagement> section of the BizTalk configuration file to support up to 100 concurrent connections from each of our 2 BizTalk send servers to the web servers of the application. The problem we were facing was that the BizTalk side was reporting a significant number of timeouts when calling the web service.   One of the biggest issues was the challenge of being able to correlate a message from BizTalk to the IIS log in the .net application and the custom logs in the application especially when there was a fairly large number of servers hosting the web services.  However the key moment came when we were able to identify a specific call which had taken 40 seconds to execute on the server (yes a long time I know but that's a different story!).  Anyway we were able to identify that this had timed out on the BizTalk side.  Based on the normal 2 minute timeout we knew something unexpected was going on. From here I decided to do some experimentation and I wanted to start outside of BizTalk because my hunch was this was not a BizTalk behaviour but something which was being highlighted by BizTalk because of our large load.     Server-side - Sample Web Service To begin with I created a sample web service.  Nothing special just a vanilla asmx web service hosted in IIS6 on Windows 2003 Standard Edition.  The web service is just a hello world style web service as shown in the below picture.  The only key feature is that the server side web method has a 30 second sleep in it and will trace out some information before and after the thread is set to sleep.      In the configuration for this web service there again is nothing special it's pretty much the most plain simple web service you could build. Client-Side To begin looking at what was happening with our example I created a number of different ways to consume the web service. SoapHttpClientProtocol Example I created a small application which would use a normal proxy generated to call the web service.  It would iterate around a loop and make calls using the begin/end methods so I can do this asynchronously.  I would do a loop of 20 calls with the ConnectionManager configuration section supporting only 5 concurrent connections to the server.     <connectionManagement> <remove address="*"/> <add address = "*" maxconnection = "12" /> <add address = "http://<ServerName>" maxconnection = "5" />                         </connectionManagement> </system.net>     The below picture shows an example of the service calling code, key points are: I have configured the timeout of 40 seconds for the proxy I am using the asynchronous methods on the proxy to call the web service         The Test I would run the client and execute 21 calls to the web service.   The Results  Below is the client side trace showing what's happening on the client. In the below diagram is the web service side trace showing what's happening on the server Some observations on the results are: All of the calls were successful from the clients perspective You could see the next call starting on the server as soon as the previous one had completed Calls took significantly longer than 40 seconds from the start of our call to the return. In fact call 20 took 2 minutes and 30 seconds from the perspective of my code to execute even though I had set the timeout to 40 seconds     WSE 2 Sample In the second example I used the exact same code to call the web service again with a single exception that I modified the web service proxy to derive from WebServiceClient protocol which is part of WSE 2 (using SP3).  The below picture shows the basic code and the key points are: I have configured the timeout of 40 seconds for the proxy I am using the asynchronous methods on the proxy to call the web service        The Test This test would execute 21 calls from the client to the web service.   The Results  The below trace is from the client side: The below trace is from the server side:   Some observations on the trace results for this scenario are: With call 4 if you look at the server side trace it did not start executing on the server for a number of seconds after the other 4 initial calls which were accepted by the server. I re-ran the test and this happened a couple of times and not on most others so at this point I'm just putting this down to something unexpected happening on the development machine and we will leave this observation out of scope of this article. You can see that the client side trace statement executed almost immediately in all cases All calls after the initial few calls would timeout On the client side the calls that did timeout; timed out in a longer duration than the 40 seconds we set as the timeout You can see that as calls were completing on the server the next calls were starting to come through The calls that timed out on the client did actually connect to the server and their server side execution completed successfully     Elaboration on the findings Based on the above observations I have drawn the below sequence diagram to illustrate conceptually what is happening.  Everything except the final web service object is on the client side of the call. In the diagram below I've put two notes on the Web Service Proxy to show the two different places where the different base classes seem to start their timeout counters. From the earlier samples we can work out that the timeout counter for the WSE web service proxy starts before the one for the SoapHttpClientProtocol proxy and the WSE one includes the time to get a connection from the pool; whereas the Soap proxy timeout just covers the method execution. One interesting observation is if we rerun the above sample and increase the number of calls from 21 to 100,000 then for the WSE sample we will see a similar pattern where everything after the first few calls will timeout on the client as soon as it makes a connection to the server whereas the soap proxy will happily plug away and process all of the calls without a single timeout. I have actually set the sample running overnight and this did happen. At this point you are probably thinking the same thoughts I was at the time about the differences in behaviour and which is right and why are they different? I'm not sure there is a definitive answer to this in the documentation, or at least not that I could find! I think you just have to consider that they are different and they could have different effects depending on your messaging solution. In lots of situations this is just not an issue as your concurrent requests doesn't get to the situation where you end up throttling the web service calls on the client side, however this is definitely more common with an integration broker such as BizTalk where you often have high throughput requirements.  Some of the considerations you should make Based on this behaviour you should be aware of the following: In a .net application if you are making lots of concurrent web service calls from an application in an asynchronous manner your user may thing they are experiencing poor performance but you think your web service is working well. The problem could be that the client will have a default of 2 connections to remote servers so you should bear this in mind When you are developing a BizTalk solution or a .net solution with the WSE 2 stack you may experience timeouts under load and throttling the number of connections using the max connections element in the configuration file will not help you For an application using WSE2 or SoapHttpClientProtocol an expired timeout will not throw an error until after a connection to the server has been made so you should consider this in your transaction and durability patterns     Our Work Around In the short term for our specific scenario we know that we can handle this by just increasing our timeout value.  There is only a specific small window when we get lots of concurrent traffic that causes this scenario so we should be able to increase the timeout to take into consideration the additional client side wait, and on the odd occasion where we do get a timeout the BizTalk send port retry will handle this. What was causing our original problem was that for that short window we were getting a lot of retries which significantly increased the load on our send servers and highlighted the issue.  Longer Term Solution As a longer term solution this really gives us more ammunition to argue a migration to WCF. The application we are calling has some factors which limit the protocols we can use but with WCF we would have more control on the various timeout options because in WCF you can configure specific parts of the timeout. Summary I've had this blog post on my to do list for ages but hopefully it will be useful to some people to just understand this behaviour and to possibly help you with some performance issues you may have. I do not believe there is too much in the way of documentation particularly around WSE2 and ASMX in this area so again another bit of ammunition for migrating to WCF. I'll try to do a follow up post with the sample for WCF to show how this changes things.

• Dynamic/Adaptive RLE

  - by Lucius

  So, I'm developing a 2D, tile based game and a map maker thingy - all in Java. The problem is that recently I've been having some memory issues when about 4 maps are loaded. Each one of these maps are composed of 128x128 tiles and have 4 layers (for details and stuff). I already spent a good amount of time searching for solutions and the best thing I found was run-length enconding (RLE). It seems easy enough to use with static data, but is there a way to use it with data that is constantly changing, without a big drop in performance? In my maps, supposing I'm compressing the columns, I would have 128 rows, each with some amount of data (hopefully less than it would be without RLE). Whenever I change a tile, that whole row would have to be checked and I'm affraid that would slow down too much the production (and I'm in a somewhat tight schedule). Well, worst case scenario I work on each map individually, and save them using RLE, but it would be really nice if I could avoind that. EDIT: What I'm currently using to store the data for the tiles is a 2D array of HashMaps that use the layer as key and store the id of the tile in that position - like this: private HashMap< Integer, Integer [][]

• Effective way to check if an Entity/Player enters a region/trigger

  - by Chris

  I was wondering how multiplayer games detect if you enter a special region. Let's assume there is a huge map that is so big that simply checking it would become a huge performance issue. I've seen bukkit (a modding API for Minecraft servers) firing an Event on every single move. I don't think that larger games do the same because even if you have only a few coordinates you are interested in, you have to loop through a few trigger zone to see if the player is inside your region - for every player. This seems like an extremely CPU-intense operation to me even though I've never developed something like that. Is there a special algorithm that is used by larger games to accomplish this? The only thing I could imagine is to split up the world into multiple parts and to register the event not on the movement itself but on all the parts that are covered by your area and only check for areas that are registered in the current part. And another thing I would like to know: How could you detect when someone must have entered a trigger but you never saw him directly in it since his client only sent you an move packet shortly before entering and after leaving the trigger area. Drawing a line and calculate all colliding parts seems rather CPU intensive if you have to perform it every time.

• Message Queue: Which one is the best scenario?

  - by pandaforme

  I write a web crawler. The crawler has 2 steps: get a html page then parse the page I want to use message queue to improve performance and throughput. I think 2 scenarios: scenario 1: structure: urlProducer -> queue1 -> urlConsumer -> queue2 -> parserConsumer urlProducer: get a target url and add it to queue1 urlConsumer: according to the job info, get the html page and add it to queue2 parserConsumer: according to the job info, parse the page scenario 2: structure: urlProducer -> queue1 -> urlConsumer parserProducer-> queue2 -> parserConsumer urlProducer : get a target url and add it to queue1 urlConsumer: according to the job info, get the html page and write it to db parserProducer: get the html page from db and add it to queue2 parserConsumer: according to the job info, parse the page There are multiple producers or consumers in each structure. scenario1 likes a chaining call. It's difficult to find the point of problem, when occurring errors. scenario2 decouples queue1 and queue2. It's easy to find the point of problem, when occurring errors. I'm not sure the notion is correct. Which one is the best scenario? Or other scenarios? Thanks~

• Two different domains as one user session

  - by Mathew Foscarini

  I have two websites that are run as the same service. Each domain offers articles from a different market. At the top of each page the two domains are shown as menu options. If a user clicks one they can switch to the other domain. See here: http://www.cgtag.com Each domain has a different Google Analytics account, and when a user switches domains Google is counting this as a new session. It's listing the other domain as the "referral" for that new session. When the user switches back to the first domain Google is counting this as a returning visitor. This is messing up my reports. Showing returning visitors values that are higher than reality. It's also increasing hits on landing pages when the user switches, and listing the other domain as a referral site. I've found tips on how to list two domains as one website, but that results in merging the data. I want to keep the two domains separate so that I can track each ones performance, but I don't want to count domain changes as new sessions. Maybe something like treating the two domains as subdomains.

• How to design highly scalable web services in Java?

  - by Kshitiz Sharma

  I am creating some Web Services that would have 2000 concurrent users. The services are offered for free and are hence expected to get a large user base. In the future it may be required to scale up to 50,000 users. There are already a few other questions that address the issue like - Building highly scalable web services However my requirements differ from the question above. For example - My application does not have a user interface, so images, CSS, javascript are not an issue. It is in Java so suggestions like using HipHop to translate PHP to native code are useless. Hence I decided to ask my question separately. This is my project setup - Rest based Web services using Apache CXF Hibernate 3.0 (With relevant optimizations like lazy loading and custom HQL for tune up) Tomcat 6.0 MySql 5.5 My questions are - Are there alternatives to Mysql that offer better performance for what I'm trying to do? What are some general things to abide by in order to scale a Java based web application? I am thinking of putting my Application in two tomcat instances with httpd redirecting the request to appropriate tomcat on basis of load. Is this the right approach? Separate tomcat instances can help but then database becomes the bottleneck since both applications access the same database? I am a programmer not a Db Admin, how difficult would it be to cluster a Mysql database (or, to cluster whatever database offered as an alternative to 1)? How effective are caching solutions like EHCache? Any other general best practices? Some clarifications - Could you partition the data? Yes we could but we're trying to avoid it. We need to run a lot of data mining algorithms and the design would evolve over time so we can't be sure what lines of partition should be there.
